BUNGr-LOCK.

To all whom 'it may concern Be it known that l, BRUNO O. Rmonxnn'r, asubject et the Emperor of Germany, residing at N ew York, in the countyot' New York and State of New York, have invented certain new and usefulImprovements in Bang-Locks, of which the following is a specification.

rlhis invention comprehends certain new and uset'ul improvements inbangs and relates more particularly to means whereby a bung may belocked into a barrel to prevent an unauthorized person removing thesame.

The primary object of the invention resides in the provision of a bunglof this nature which shall be of extremely simple construction, cheap tomanufacture, and which may be unlocked only by the use oil a key.

A further and more specific object of the invention is to provide abarrel bung having a spring-pressed pawl adapted for cngagement withteeth formed on the bushing, said pawl being movable by a key insertedinto the bunff.

There is a great need tor some means whereby barrels containingwine,liquor, oil, gasolenc, or the like, may be securely closed and locked soas to prevent their contents being wasted or stolen. My improved bung isdesigned to answer this purpose.

With these and other objects in view, as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination, and arrangement of parts, as willbe hereinafter fully described and claimed.

For a complete understanding of the invention, reference is to be had tothe following description and accompanying drawings, in which,

Figure 1 is a top plan view of my improved barrel bung, Fig. 2 is atransverse sectional view through the bung and bushing therefor, and,Fig. 3 is a longitudinal sectional view of my invention.

Referring` in detail to the drawings by numerals, 1 designates a portionot' a container such as a Cask, tank, or barrel, provided with acircular opening in which is positioned a casing or bushing 2. Thebushing comprises an essentially cylindrical body portion, having itsinterior diameter reduced and threaded` as at 3, whereby a shoulder t isformed. The inner end of the reduced portion 3 is 'further reduced indiameter by Spccicaton of Letters Patent.

the downwardly and inwardly inclined wall 5 and terminates in a verticalwall G. The bushing 2 formed intermediate its ends, with the annularflange 7, which is apertured to receive the 'lfastening members 8, whichsecure the flange to the, container 1. A. rubber gasket 9 is interposedbetween thc interior oit the container 1 and the flange 7 to provide anair-tight joint. It desired, the exterior ot the bushing` may be reducedat its inner end, as shown at 10.

A cylindrical bung 11 having a reduced threaded intermediate portion 1Qand a ii'urther reduced inner end portion 13, is positioned forlongitudinal and rotational movement within the bushing 2. The exteriorot the bung` conforms in all essential respects to the interior ot thebushing and therefore when said bung is screwed tightly into position, aclose joint is 'formed around its inner end walls, and the shoulder 14termed by the reduced portion 12 bears tightly against a rubber gasketf1.5, thereby producing an air-tight. joint. The outer end of the bungis lormed with the {lange 1G for engagei'nent with thc outer edge ot'the bushing 2 and is iturthcr provided with the wrench openings 17 toreceive a tool, by means oi which the bung` may be either screwed intoor out ot the bushing.

My improved locking means includes a pawl 1S mounted intermediate itsends upon the pivot rod 19, which rod extends across a recess 2O formedin one side ol the bung head 11. The recess is enlarged at one end toprovide roem for a key, which will be dcscribcd later. A tlat metalspring 21 is fixed at one end to the end wall of the recess 2O and bearsat its other end against the pawl 18, thereby holding the same normallyin engagement with the teeth 22, formed upon the interior of the bushing2 adjacent its outer end. It will be noted upon reference to Fig. 3,that the teeth 2Q extend `from the shoulder 23 to the outer end of thebung and that the tooth engaging end of the pawl 1S is normallyproject-ed out oi thc recess 2O into engagement with one ot these teeth.Collars 241; positioned upon the pivot rod 19 hold the pawl 18 away fromengagement with the top and bottom walls o'l. the recess Q0. lVhen thebung is at the extremity of its inward movement, the pawl 1S engages theteeth 22 near their inner ends, but it will be seen that since theseteeth are o1 an extreme length, it is possible to lock the bung nomatteil how far it is screwed into the bushing 2. To provide fordisengaging the pawl 18 from the teeth 22, l provide the keyhole 25opening upon the outer face of the bung and communicating with therecess 20, and the circular portion of the keyhole extends somewhatbelow the bottom wall of the recess, as indicated at 26. To release thepawl from locking engagement, a suitable key 27 is placed in the keyholeand rotated so as to engage the pawl and rotate it against the pressureof the spring 2l. W hen this has been done, a wrench may be inserted inthe openings 17 and the bung rotated, either inwardly or outwardly.

It is to be understood that while have shown and described the preferredembodiment of 'my invention, I do not wish to be limited to this exactconstruction, and arrangement of parts. H desired, I may apply myimproved locking means to bungs of various constructions, which bungsmay be, if desired, equipped with suitable faucets or spigots.

Having thus described my invention, what I claim is :L-

l. The combination with a container having an opening formed therein, ofa cylindrical bushing positioned within said opening, the interior ofthe bushing being threaded for a portion of its length adjacent itsinner end and provided adjacent its outer end with a plurality oflongitudinal teeth, a threaded bung positioned within said busliing andprovided intermediate its ends with a recess, a pawl pivotedintermediate its ends within said recess and adapted for engageinent atone end with said teeth, means ior holding said pawl normally againstthe teeth, the bung being formed with a keyhole, 40

and akey adapted to be rotated within said keyhole for the purpose ofdisengaging the pawl from the teeth.

2. The combination with a container having an opening formed therein, ofa bushing positioned Within said opening, the bushing being internallythreaded for a portion of its length and provided adjacent itsV outerend on its Vinterior wall with a plurality of longitudinal teeth, athreaded bung posi- 5e tioned within said bushing andA formedintermediate its ends with a recess, said recess opening upon theperipheryy of the bung, a pawl pivoted intermediate4 its ends withinsaid recess, a flat metal spring secured at 5K5 one end to the innerwall of the recess and bearing at its other end against said pawlwhereby the latter is held in engagement with the teeth, the bung beingformed within a keyhole, a key being adapted to' be ro- 60 BRUNOYO.RECHAR'DT.
